Abstract

An unlock mechanism includes a socket, a handle, a driving member, a driving shaft and a moving member. The socket includes a pivot hole. The handle includes a pivot shaft. The pivot shaft is rotatably disposed in the pivot hole. The driving member is movably disposed in the socket and sleeved on the pivot shaft. The driving member includes an inclined surface. The driving shaft is disposed on the pivot shaft and abuts against the inclined surface. The moving member is connected to the driving member. The handle rotates to drive the driving shaft to rotate, the driving shaft pushes the inclined surface to drive the driving member to move, and the driving member drives the moving member to move.

First claim

What is claimed is:

1. An unlock mechanism comprising:
a socket comprising a pivot hole;
a handle comprising a pivot shaft, the pivot shaft being rotatably disposed in the pivot hole;
a driving member movably disposed in the socket and sleeved on the pivot shaft, the driving member comprising an inclined surface;
a driving shaft disposed on the pivot shaft and abutting against the inclined surface; and
a moving member connected to the driving member;
wherein a rotating direction of the handle is perpendicular to a moving direction of the moving member; when the handle rotates to drive the driving shaft to rotate, the driving shaft pushes the inclined surface to drive the driving member to move, and the driving member drives the moving member to move toward an outside of the socket.

2. The unlock mechanism of claim 1 , further comprising an operating member movably disposed in the handle, the operating member comprising a press portion and a restraining portion, the press portion being exposed from the handle, the handle further comprising a through hole, the through hole being located at an end of the pivot shaft, the socket further comprising a restraining recess, the restraining recess communicating with the pivot hole, the restraining portion passing through the through hole to engage with the restraining recess to lock the handle, the press portion being pressed to disengage the restraining portion from the restraining recess to unlock the handle.

3. The unlock mechanism of claim 2 , further comprising a first elastic member disposed in the handle, opposite ends of the first elastic member abutting against the handle and the operating member respectively.

4. The unlock mechanism of claim 1 , further comprising a fixing shaft disposed on the pivot shaft to rotatably restrain the handle on the socket.

5. The unlock mechanism of claim 1 , wherein the inclined surface is a curved surface.

6. The unlock mechanism of claim 1 , wherein the driving member further comprises an extending portion and the moving member is connected to the extending portion.

7. The unlock mechanism of claim 6 , wherein the moving member is formed on the extending portion integrally.

8. The unlock mechanism of claim 1 , wherein the socket further comprises an accommodating recess, a shape of the accommodating recess corresponds to a shape of the driving member, and the driving member is accommodated in the accommodating recess.

9. The unlock mechanism of claim 1 , further comprising a cover, the socket further comprising an opening, the cover being movably disposed on the socket and covering the opening.

10. The unlock mechanism of claim 1 , further comprising a second elastic member disposed in the socket, opposite ends of the second elastic member abutting against the socket and the driving member respectively.

11. The unlock mechanism of claim 1 , further comprising a third elastic member disposed in the socket and sleeved on the moving member, opposite ends of the third elastic member abutting against the socket and the moving member respectively.

12. The unlock mechanism of claim 1 , further comprising a torsion spring, opposite ends of the torsion spring being connected to the socket and the handle respectively.

13. The unlock mechanism of claim 12 , wherein the pivot shaft comprises a pillar and the torsion spring is sleeved on the pillar.

14. A server comprising:
a chassis;
at least one rail disposed at a side of the chassis;
at least one engaging mechanism disposed on the at least one rail; and
at least one unlock mechanism disposed on the chassis, each unlock mechanism comprising:
a socket comprising a pivot hole;
a handle comprising a pivot shaft, the pivot shaft being rotatably disposed in the pivot hole;
a driving member movably disposed in the socket and sleeved on the pivot shaft, the driving member comprising an inclined surface;
a driving shaft disposed on the pivot shaft and abutting against the inclined surface; and
a moving member connected to the driving member;
wherein the handle rotates to drive the driving shaft to rotate, the driving shaft pushes the inclined surface to drive the driving member to move, and the driving member drives the moving member to move toward the engaging mechanism to push the engaging mechanism.

15. The server of claim 14 , wherein the unlock mechanism further comprises an operating member movably disposed in the handle, the operating member comprises a press portion and a restraining portion, the press portion is exposed from the handle, the handle further comprises a through hole, the through hole is located at an end of the pivot shaft, the socket further comprises a restraining recess, the restraining recess communicates with the pivot hole, the restraining portion passes through the through hole to engage with the restraining recess to lock the handle, and the press portion is pressed to disengage the restraining portion from the restraining recess to unlock the handle.

16. The server of claim 14 , wherein the unlock mechanism further comprises a fixing shaft disposed on the pivot shaft to rotatably restrain the handle on the socket.

17. The server of claim 14 , wherein the socket further comprises an accommodating recess, a shape of the accommodating recess corresponds to a shape of the driving member, and the driving member is accommodated in the accommodating recess.

18. The server of claim 14 , wherein the unlock mechanism further comprises a cover, the socket further comprises an opening, and the cover is movably disposed on the socket and covers the opening.

19. The server of claim 14 , wherein a number of the at least one rail is two, a number of the at least one engaging mechanism is two, a number of the at least one unlock mechanism is two, two rails are disposed at opposite sides of the chassis, two engaging mechanisms are disposed on the two rails, two unlock mechanisms are disposed at opposite sides of the chassis with respect to the two engaging mechanisms, and rotating directions of two handles of the two unlock mechanisms are opposite.
